Travel tip: If you’re trying to smuggle cash into Panama, start using the train.

Three Honduran men were arrested at Panama City’s international airport after police found $7.2 million, mostly in $100 bills, in secret compartments in eight pieces of luggage. According to this video from Newsy (Newsy? Really? Really.), officials in Panama believe the money was connected to a drug cartel. Thirty-two officers and airport security staffers have been suspended as a result of the find.
